Rehospitalization after initial rehabilitation for acute spinal cord injury: incidence and risk factors.
Many acute spinal cord injury (SCI) patients require rehospitalization after discharge from initial rehabilitation. Previous studies of rehospitalization for these patients have been cross-sectional with respect to time since injury (in years), and have not allowed for comparison of patients with equal exposure to the risk of medical complications once they have reentered the community. To examine the incidence, cause, and monetary cost of rehospitalizations during the first year after discharge from initial rehabilitative care (day 365), the medical records of 88 consecutive, acute SCI patients who completed initial rehabilitation at a regional model SCI care system were reviewed. Cases were excluded from the study if the patient was lost to follow-up before day 365. All readmissions to the regional SCI care system during the follow-up period were reviewed for primary diagnosis, length of stay (LOS), and hospital charges incurred. Thirty-four patients (39%) were readmitted at least once by day 365. There was a total of 47 readmissions; mean LOS was 11.9 +/- 2.1 days per admission (+/- 1SE), and mean hospital charge per admission was $9,683. Univariate comparisons between the characteristics of patients who were readmitted vs those who were not indicated that the readmitted group was less educated (11.8 +/- 2.1 years vs 12.9 +/- 0.3 years, p less than 0.05) and had a substantially longer initial rehabilitation LOS (88.9 +/- 6.6 days vs 72.9 +/- 5.1 days, p less than 0.05). Readmissions were less common among patients who were discharged at Frankel class C or D (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
